AUXILIARY HEATER FOR BROODERS Filed Jan. 14, 1928 Patented Sept. 18, 1934 warren srarss PATENT or ies i 14 Claims.

This invention relates to brooders, an object of the invention being to provide an auxiliary heating element for operation independent of the usual heating elements under the hover, the same being arranged in a damper controlled air duct formed between a pair of insulated walls formed in rear of the brooder for efficiently increasing room temperature in the brooding room by opening the damper.

Another object of the invention is the provision of auxiliary heating elements comprising heating pipes through which hot water is circulated, the pipes extending through air ducts arranged in the rear of brooders in brooding rooms, the same being found very practical in connection with colony brooders having a plurality of brooding rooms through all of which the pipes extend.

A further object of the invention is to provide an auxiliary heater in connection with a brooding system in which cool air passes to the brooder through a passageway arranged under the floor of the brooding rooms, said auxiliary heater also receiving air from the passageway and working entirely independent of the system of heat control under the hover and being arranged for in-'- creasing entire room temperature.

It is also an object of the invention to provide an auxiliary heater of the above mentioned character, which is simple and substantial in construction, which can be manufactured economically in connection with brooders, and which will be thoroughly eflicient and practical in use.

I With the foregoing and other objects in view, iwhich will be apparent as the description proceeds, the invention resides in the construction and arrangement of parts, as hereinafter described and claimed, it being understood that changes can be made within the scope of what 'is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein:

Figure 1 is a vertical section through a brooder showing my improved auxiliary heater associated therewith,

Figure 2 is a vertical section taken on line 22 of Figure 1, and

Figure 3 is a fragmentary section showing a slightly modified form of the invention.

Referring to the drawing, the numeral 10 generally designates either the side walls of a brooder room or the partitions in such a room forming separate units of a brooder of the construction shown in my Patent No. 1,592,377 entitled Golony brooder, mypending application entitled Colony brooder, filed January 21, 1927, Serial No; 162,527, and the application Serial Number 245,799, filed of even date entitled Brooder house, in which are disclosed adjustable hovers 11 carried by a rear wall 12 and having thereunder a plurality of heat radiating pipes 13 about which air is circulated for obtaining hover temperature. The air circulated about the heat radiating pipes 13 passes under the floor 14 of the brooding room through a passageway 15 such as that shown in my application above mentioned entitled Brooder house. In such application, the cool air passes downwardly and enters the passageway 15 at the forward side of the house and then passes rearwardly and enters the brooding room through an opening 16 in the floor at the rear of the brooding room where the brooder is arranged, said brooder being positioned over the opening so that air passing through the opening 16 passes around the heat radiating pipes 13.

When using brooders and brooding houses of the above mentioned character in northern countries where the climate is very cold and blustery, proper hover temperature is had, but often entire room temperature of the desired degree is a little difficult to obtain. Therefore, I have provided an auxiliary heater for increasing room temperature without affecting hover temperature.

In carrying out the invention, the brooder is positioned in the brooding room a sufiicient distance from the rear wall 17 thereof for permitting the placing therebetween of a partition 18, said partition 18 being reinforced at its upper and lower edges by means of strips 19 and 20 respectively which extend across and are attached to the end members of the brooder. As the end members of the brooder have cleats extending down their forward and rearward edges, the strips 19 and 20 as well as the insulating partition 18 may be attached to said cleats and abut against the end members. The partition 18 is spaced from the rear wall 12 of the brooder for providing an air'duct or passageway 21 which extends downwardly to the floor 14 of the brooding room and is in communication with the passageway 15 under the floor of the brooding room through the opening 16. Across the opening 16 is arranged wire mesh material or the like 22. It can thus be seen that air circulating under the floor 14 through the passageway 15 will not only pass arcund the heat radiating pipes 13 but will pass upwardly through the air duct or passageway21. Extending longitudinally of the air duct at the lower portion thereof is a pair'of heat radiating pipes 23 and 24 around which the air passing up the air duct 21 must pass. By referring to Figure 1 of the drawing, it can be seen that the pipes 23 and 24 are arranged one above the other with the pipe 23 slightly in advance of the pipe 24 so as to eliminate to a great extent the direct passage of air at either side of both pipes, thus causing to a certain extent the air to wind around the heat radiator pipes. The pipes 23 and 24 are connected with the heater so that the pipe 28 forms a flow pipe and the pipe 24 a return pipe forming circulation from and to the heater.

At the upper end of the air duct or passageway 21 hingedly connected to the strip 19 is a damper 25 which may be swung to various adjusted positions so as to regulate the flow of air through the air duct or passageway 21. Attached to the rear wall 12 of the brooder is a rest strip 26 which is engaged by the damper 25 when said damper is in closed position so as to form a stepped seal as well as means for limiting downward movement of the damper 25. The damper 25 has connected thereto a chain or other flexible element 2'7 which is adapted to be engaged by a hook 28 carried by the rear wall of the brooder house in order to hold the damper 25 in adjusted position. Itcanbeseen that when the damper 25 is open air after passing around the heat radiating pipes 23 and 24 will be permitted to escape from the air duct or passageway 21 and pass into the brooding room for forming an auxiliary means for heating the brooding room.

It is to be noted that the strip 20 which is attached to the lower edge of the partition 18 is spaced slightly above the opening 16 in the floor 14 and that the partition 18 is spaced slightly from the rear wall 17 of the brooding house, which will form an air space communicating with the interior of the room and the passageway 15 for preventing the cold air exteriorly of the building from cooling or otherwise afiecting the warm air either in or passing through the air duct or passageway 21.

In Figure 3 of the drawing, the heat radiating pipes 23 and 24 are illustrated one directly above the other, but in order to prevent air from passing directly to either side of the heat radiating pipes, baifie strips 29 are attached to the rear wall 12 of the brooder and the strip 20 to which the partition 18 is attached. One of the bafiie strips 29 is arranged above and to the forward side of the heat radiating pipes, while the other bafile strip is arranged to the rear and between the two heat radiating pipes, thus providing an obstructed, tortuous passageway through which the air must pass in order topass upwardly through the air duct or passageway 21, the same serving the same purpose as staggeredly positioning the heating pipes 23 and 24 as shown in the preferred form of my invention.

During ordinary weather conditions, it may not be necessary to use the auxiliary heater in order to provide proper room temperature. In such case, the chain may be released from the hook' 28 and the damper 25 closed, and the heat remains confined in the air duct or passageway 21. The auxiliary heater works entirely independent of the temperature under the hover so that the closing of the damper 25 will not affect the hover temperature. When the damper is closed, the heat is held in the passageway or air duct 21 due to the insulated walls of the air duct or passageway and none will escape to the room, due to the tendency of heat to rise. When the damper 25 is opened, a rapid circulation around the auxiliary heating element and through the air duct or passageway 21 is had, which will quickly Warm the entire room without interfering with the circulation around the regular hover heat radiating pipes. In practice it has been found that the room temperature usually rises at least 10 higher when the damper is opened than when the brooders are used without auxiliary heaters. The use of an auxiliary heater of this character is especially desirable in northern countries where the climate is very cold and also where hatcherymen are placing small chicks beneath the hovers every few days and it is desired to have the room heated a little more for small chicks.

It is of course understood that when using my improved auxiliary heaters in connection with colony brooders having a plurality of aligned brooding rooms having aligned brooders therein the heat radiating pipes 23 and 24 extend through all of the brooding rooms-and form heating means for all brooding rooms. The various brooding rooms may be regulated by means of the dampers 25 so that certain brooding rooms may be held at different temperatures from that of other brooding rooms.
